FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining stable in storage liquid superbasic salt of alkali or alkali earth metal. Method includes reaction of mixture of alkali or alkali earth base and aliphatic or aromatic carboxylic acid, in which equivalent ratio of metal base and carboxylic acid constitutes more than 1:1, in presence of liquid hydrocarbon, and carboxylation of reaction mixture in presence of 1,3-diketone. Also claimed are liquid superbasic salt of alkali or alkali earth metal, suitable for application in mixed metal stabilisers and halogen-containing polymer composition.
EFFECT: invention makes it possible to obtain stable in storage liquid superbasic salt of alkali or alkaliearth metal, possessing thermostabilising action.
